The
second hand, which travels once round the face in a minute, is the one
with the little ring at its end near the centre.
Our dial indicates the
exact time when its owner stopped the watch.
You will notice that the
three hands are nearly equidistant.

The hour and minute hands point to
spots that are exactly a third of the circumference apart, but the
second hand is a little too advanced.

An exact equidistance for the
three hands is not possible.
Now, we want to know what the time will be
when the three hands are next at exactly the same distances as shown
from one another.
